SEATTLE -- Marshawn Lynch rushed for 91 yards and a touchdown, Russell Wilson threw a touchdown pass to rookie Paul Richardson, and the Seattle Seahawks knocked archrival San Francisco from playoff contention 17-7 Sunday.

The defending Super Bowl champions remained in contention for a division title and No. 1 seed in the NFC.

After a sluggish, sloppy first half, Seattle (10-4) awoke in the final 30 minutes behind the running of Lynch and a defense that shut out the 49ers, holding them to 67 yards. Colin Kaepernick was sacked six times and the 49ers didn't run a play past the Seattle 38 in the second half.

Lynch scored on a 4-yard run late in the third quarter and the Seahawks took advantage of a short field on their next drive, capped by Wilson's strike to Richardson.

The loss and Detroit's win eliminated San Francisco (7-7) from contention.
